Chocolate Banana Nut Cake

I have been working on this recipe for a while. It is a really great snack cake.

5 bananas mashed
3/4 cup butter
6 oz. semi-sweet chocolate
1/8 cup cocoa powder
1/2 cup white sugar + 1/2 cup brown sugar
2 tsp. baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
3 eggs
1/2 cup milk
1 tablespoon vanilla
1/2 cup ground nuts (just pulse in a blender or food processor)
1 cup all purpose flour + 1/2 cup whole wheat flour
1 cup chocolate chips

1. Preheat oven to 350 degrees
2. Melt the butter with the chocolate. Add chocolate mixture to the bananas. Add the cocoa ( I like the combo of melted chocolate and cocoa powder) Mix in the sugars, baking powder, soda, and salt. Add the eggs, milk, and vanilla.
3. Blend in the ground nuts and add the flour. Finally stir in the chocolate chips.
Bake for 50-55 minutes.
4. Serve dusted with powdered sugar.
